IPC: H02P5/52
Filed: 1990-08-08
Abstract: There are provided servo motors (1) and servo control units (2) for n shafts. A setting device previously sets parameters for servo control individually for each of the n shafts and previously sets parameters for servo control for a synchronizing operation. Data which determines synchronization conditions of servo motors of respective shafts is applied, when required, by an input device independently of setting by the setting device. The data which determines the synchronization conditions includes, for example, data of combination of synchronized shafts and data of section for synchronization. A moving pattern preparation device (5) determines servo motor shafts to be synchronously controlled on the basis of the synchronization condition determining data applied through the input device and prepares a moving pattern to a target position on the basis of the parameters for servo control set by the setting device with respect to each servo motor shaft to be synchronously controlled. Positioning control data corresponding to the prepared moving pattern is supplied to the servo control unit corresponding to each shaft to synchronously control the servo motor corresponding to each shaft. The   synchronizatin conditions can be changed, when required, by the input device.

Abstract: A bone mineral content measuring apparatus for obtaining the bone mineral content of an object to be examined by irradiating X-rays onto the object and measuring the X-rays which have passed through the object. An X-ray generating device generates X-rays having a continuous spectrum. The X-rays generated pass through an X-ray filter before the irradiation of the object or after the transmission of the object. The X-ray filter is composed of a substance having an X-ray absorbing characteristic with the K-absorption edge at a predetermined energy value. The X-rays which have passed through the X-ray filter and the object are detected by the X-ray detector. A data analyzer inputs the detected X-ray detection data and analyzes the bone mineral content of the object on the basis of the X-ray absorbing characteristic of the X-ray filter.

Abstract: An optical component of the integrated type is produced by coating a substrate (10) with a layer (12) of photo-polymerisable material which is substantially free of any thermal catalyst, exposing the layer to radiation at a first temperature via a mask for example so that zones of the layer are selectively polymerised in accordance with a predetermined pattern corresponding to the configuration of the desired optical component, heat treating the layer to post cure the polymerised zones, and thereafter flood illuminating the layer at a second temperature lower than the first to polymerise the previously unexposed areas. In this way, an enhanced refractive difference between the pattern and the surrounding areas can be achieved.

Abstract: A combined range laser scanner and method for electro-optically reading indicia such as bar codes having parts of different light reflectivity which utilizes two laser diode optical illumination systems optimally focused for different working ranges. A first laser illumination system is optimized for contact operation and has a range extending to approximately two feet. The second laser illumination system is optimized for longer range scanning from approximately two to seventeen feet, and the two laser scanning systems are integrated into one combined range laser scanner. The combined range laser scanner incorporates therein logic circuitry which enables either laser illumination system as required fro the particular scanning application. Depending upon which laser illumination system is selected, the laser spot speed (e.g. amplitude of the drive signal for the scanning motor) is controlled to limit the frequency of received light signals to that of standard signal processing and decoding circuits. Scanning is achieved with a common oscillating mirror element driven by a scanning motor, and the amplitude of the applied scanning motor driving signal is greater for the first laser illumination system optimized for contact or short range operation and less for the second laser illumination system for longer range scanning.
